Description

(54) FLUID LEVEL REGULATOR IN SUPPLEMENTS

I

The invention relates to hydraulic structures and can be used at water intake assemblies and gateways-regulators for automatic two-way flow control, taking into account the flow of sediment and float, their objects.

A mixed-type automatic regulator is known, consisting of a sector gate with a hermetic capacity and a counterweight to balance the moments acting on the gate, and the hydraulic system of the sensors.

The working capacity of the sector gate through the inlet is connected to the upper pool, and the outlet to the bottom. The outlet is blocked by the elastic diaphragm of the valve, which is controlled by a system of sensors located in the upper and lower pools. Sensors are activated depending on which level of the pool needs to be adjusted 1.

The disadvantages of this design are the inability to skip the fin and completely release the culvert.

A two-way shutter is known, made in the form of a filled shell.

forming a closed container attached to a concrete flatbot.

As the level increases in the downstream above the upstream level, reverse flow occurs and the tank "rolls, changes its shape, and maintains head from the downstream 2.

The disadvantages of this design are the need for additional energy sources for filling and emptying the container, the possibility of structural damage, the large dimensions of the flybet, and the presence of significant dynamic loads in the attachment unit during the "rolling of the container.

The closest technical solution

To the proposed is a device for automatic flushing of hydraulic structures from pumps, consisting of a segmented shield, lower and upper shell fixed on it and forming a loading

and balancing capacity. Tanks have input. and prefab holes. The shield axis is on the downstream side at 2/3 of the height of the shutter. In working condition, the shutter is in the vertical position and blocks the drain hole in the flushing gallery. The loading tank is filled through the inlet of the sediment sensor as the sump is filled with water. By raising the water level in the sump to the inlet of the upper balancing tank, the latter is filled. During the operation of the sedimentation tank, sediment is deposited at the shield and gradually closes the inlet of the sediment sensor. The inflow of water into the lower tank is reduced and it is emptied. Under the action of the weight of water in the upper tank, the moment changes relative to the axis of the device and the shield opens. The level in the settling tank drops sharply and the sediment flushing begins. After emptying the balancing capacity, the shield takes the initial position 3 under the influence of the weight of water in the loading capacity. The disadvantages of this design are working in two ways x (open and closed) and its difficulty adjusting levels of reach. The design cannot be used for two-sided adjustment. The purpose of the invention is the implementation of bilateral flow control taking into account the passage of sediment and fin and the complete release of the living section of the culvert. The goal is achieved by the fact that the capacity of the regulator is formed by movably interconnected two flaps, movably connected respectively to the lower ground of the shield and to a shelf rigidly connected to the banks, to which the shield is movably connected, moreover, in the closed position of the regulator, the angle between the flaps on the tank side is larger than on the pool side. FIG. 1 shows schematically the regulator in the closed position when adjusting from right to left; in fig. 2 - the same} in the closed position when adjusting from left to right. The regulator includes a shield 1 attached in the middle part to the horizontal axis 2 and a working tank 3 formed by two movably connected between them leaflets 4, one of which is movably connected to the lower part of the shield, and the other is movably connected to the shelf 5, rigidly fixed with coastal foundations. The water supply to the inside of the tank and outflow from it is controlled by a spool valve 6, consisting of a working chamber 7 and the spool 8 itself, rigidly connected with a float 9 located in the float chamber 10. The pipeline is fed to the distributor 11 from the float chamber. The tank is filled and emptied through pipeline 12. Water is drained from the distributor by pipeline 13. To prevent water leaking from the eMKOCTVi when the water level drops in two pools, an annular seal 14 is provided in the lower part of the spool chamber. 16, which are equipped with check valves 17 and 18, serve to prevent water from flowing from one pool to another. To skip transist spending, a device 19 is provided that raises the float-9 upwards. The design works as follows. When raising the level in one of the pools, for example, right, the float 9 rises and moves the spool 8 up. In this case, there is a redistribution of the incoming and outgoing water in such a way that the amount of outflowing water increases, and the incoming water decreases. As a result, the volume of water in the tank 3 decreases, the downstream pressure increases and the flaps 4 are pressed into the tank, driving the entire regulator, which opens until the preset level is restored. In the case of lowering the level of the mark against the preset, on the contrary, the spool 8 covers the hole 13, the inflow of water into the tank 3 increases. The hydrostatic pressure on the flaps 4 on the side of the tank 3 increases and the regulator is covered up until the level is restored. When adjusting the left side, the shutter work proceeds in a similar way. When skipping transist spending, it is necessary for device 19 to raise the float upwards. The flow of water into the distributor 6 will stop and the outflow will increase. The container 3 is emptied, the pressure difference acting on the flaps 4 increases, and they are moved inside the container, driven by a regulator which, turning, releases the living section of the channel. The proposed device allows for two-way regulation, sediment and fin passage, which makes the design very promising. The discharge of bottom sediments under the shield and the fin through it makes it possible to drastically increase the reliability of the entire structure. The regulator allows you to skip transist spending almost without the constraint of the living cross section of the culvert. Due to the separation of the flow along the vertical, the hydraulic regime in the pools is improved, the impact of the surface and bottom jets causes a decrease in the flow energy behind the structure, which leads to a decrease in the length of the pier, and reduces capital and operating costs.
